i I .880 E D STRUCTURAL UNIT.

Application filed August 11, 1927. Serial No. 212,244

.5 A further object is to provide a structural unit of this character which is very economical in structure and very effective for the purpose and is adapted for use in a variety of relations.

Objects relating to details and economies of construction and operation of my inven tion, will appear from the detailed description to follow.

The invention is defined and pointed out in the claims.

of my invention, a pair of reinforcing bars being indicated by dotted lines in operative relation to the support.

Fig. 2 is a fragmentary plan view.

Fig. 3 is a fragmentary section on a line corresponding to line 3-3 of Fig. 2.

In the drawing similar reference characters refer to similar parts throughout the 3:; several views.

In the embodiment illustrated in the ac companying drawing, my improved reenforcing support comprises a longitudinal rod 1 which is preferably corrugated, the corru- 1 gations being disposed'in a vertical plane.

This rod is supported by a plurality of spaced feet 2 formed of loops of wire or light rod, as may be required, these loops being elongated and disposed with their closed side I! downward forming base members 8, their arms 4 being disposed oppositely and at an angle to their base members, that is, the ends of the arms lie at an angle to the plane of the base member and at opposite sides 4 thereof.

The arms are secured by welding to the side of the longitudinal rod, as indicated at 5 in Fig. 3.

By thus disposing the arms, the tipping strain on the feet is minimized when under load and they are secured to the longitudinal rods so that they are not likely to be broken off.

The corrugations are uniformly spaced so as to constitute a unit of measure. The corrugations in the structures as manufactured for the market are one inch apart so that the bars may be easily spaced according to specifications. The corrugations also assist in retaining the bars in their spaced position as when the bars are wired to the support, they cannot slip along thereon. It is quite common practice to manufacture supports for the spacing designed for. In the applican'ts structure this is not necessary.

vThe units may be formed of standard length and cut to meet the particular requirements.

I have not attempted to illustrate. or describe certain HlOdlfiCatlOIlS and adaptations which I contemplate as I believe this disclosure will enabie those skilled in the art to embody or adapt my lll'lPlOVGlllGlltS as ma be desired.

Having thus described my invention, what I claim as new and desire-to secure by Letters Patent, i 1

1. A s :uctural unit comprising a corrugated longitudinal supporting rod disposed with its corrugations in a vertical plane, and a plurality of feet formed of elongated loops of wire disposed transversely of the longitudinal rod with their closed sides downward and constituting base members, the arms of the loops being disposed oppositely and at an angle to the base members and welded to the underside of the rod.

2. A structural unit comprising a longitudinalsupporting rod, and a plurality of feet formed of elongated loops of wire disposed transvcrsel of the longitudinal rod with their closed sides downward and constituting base members, the arms of the loops being disposed oppositely and at an angle to the base members and welded to the rod.

3. A structural unit comprising a longitudinal supporting rod, and a plurality of feet formed of elongated loops disposed transversely of said longitudinal rod with their closed sides downward and constituting base members, the arms of the loops being separated and welded to the rod in planes on opposite sidesv of the vertical plane of the base member.
